TULSA, Oklahoma - A few storms will persist for a few more hours this morning across far northern OK before dissipating later.  A few additional storms may develop later today with daytime heating across the northern third of the state but the coverage will remain low.  Any storms will produce very heavy rainfall and a threat for a few downburst of wind on occasion.   

The mid-level ridge of high pressure will expand slightly today and Saturday before shifting west and weakening early next week.  This will allow a northwest flow pattern to develop and continue for several days next week resulting in additional rain and thunderstorm chances and eventually some not as hot air.   Temperatures today will move into the mid or upper 90s with partly to mostly sunny conditions.   Heat index values will cross the 100 threshold but should not trigger heat advisories this afternoon for most locations.  

The weak front made a southward jog yesterday afternoon and brought some storms across southern Kansas and northern OK.   Most locations across the eastern third of the state missed out on the storms but a few of our neighbors did experience some activity late last night.  The Kay county area has been hammered with very heavy rainfall overnight and a few severe storm warnings.   Radar estimates suggest over 4 to 6 inches of rain and the rain continues to fall as of this posting.

 A few spotty showers and storms may continue for the next few hours and then again later this afternoon but only across far northeastern OK.  

The ridge will expand this weekend and bring us warm and muggy conditions across eastern OK.   Low temperatures will remain in the mid to upper 70s.   Afternoon highs will be in the mid to upper 90s.

Sunday into next week the mid-level ridge will retrograde and weaken.   This will bring a few storm systems across the central plains southward reaching part of Oklahoma by Sunday night with a chance for a few showers and storms.   The pattern will remain for most of next week with periodic storm chances and gradually decreasing temperatures.   A weak front should near the area Wednesday or Thursday with a better chance of rain and some noticeably cooler conditions.   Temperatures Tuesday and Wednesday will be in the lower to mid-90s but dropping into the upper 80s near 90 sometime late Thursday or Friday of next week. 

Thanks for reading the Friday morning weather discussion and blog.

Have a super great day!
